SASI-I-LOCK.

Specification of Letters Patent.

Patented Junei, 1915.;

and use the same.

This invention comprehends certain new and useful improvements in sash locks and has for its primary object to provide a device of this character which will be of such construction and operation that it may be employed for locking either one sash or both sashes against movement, as may be desired.

Another object of the invention is to provide a device of this character which will be of extremely simple construction and operation as well as highly efiicient in use and cheap to manufacture.

The invention has for a further object to provide a device of this character including a cam locking member mounted upon a pin which is slidably engaged in a support secured to one side, whereby the pin may be moved in one direction for engagement in openings in the remaining sash of a window to locktogether the two sashes, and the pin may be rotated to swing the cam locking member into engagement with-the window frame to lock the sash by which the device is carried against movement in one direction.

With these and other objects in view as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination and arrangement of parts as will be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawings, in which Figure 1 is an elevation of my improved device in use, Fig. 2 is a top plan view thereof, Fig. 3 is a longitudinal section through the same, Fig. 4 is an end elevation, and Fig. 5 is a plan view of the locking III. P Referring in detail to the drawings by W. GooDNoW,

numerals, l designates the base of the support which is adapted to be secured upon the upper rail of the lower sash 2 of a wmdowby any suitable securing members.

From the opposite longitudinal edges of the base 1, I have extended the upwardly directed parallel side members 3 of the sup port within the upper portions of which is sl dably and rotatably mounted the locking pin 4 which is provided upon one end with the head 5 by means of which it may be readlly rotated or moved longitudinally, as desired. It will be readily understood that when the pin 4 is moved inwardly, the point thereof is forced into one of the thimbles 6 positioned in suitable openings 7 in one of the side rollers of the upper sash 8, thereby locking together the lower and upper sashes of the window and preventing independent movement of the same. The locking pin 4 is provided in its body portion with the longitudinal elongated slot 9 within which extends the stop 10, which may be in the form of a driven pin or the like and is carried by the inner end 11 of the cam locking member 12 mounted upon said pin between the upstanding sides 3 of the support.

It will be readily seen that as the main portion of the cam member 12 is connected with the inner end 11 thereof by reduced neck portions 13 and has its locking face 14 adapted for engagement with the adjacent face of the window frame 15 upon rotation of the locking pin 4 in one direction, upward movement of the lower sash 2 will be prevented when the cam member 12 is in operative position and engaged with the window frame 15. It will also be readily understood that the cam locking member 12 may be moved to operative or inoperative position either when the locking pin 4 is in its outermost position or innermost position, as desired, as the pin may be rotated or moved longitudinally to lock either the lower sash against movement independently of the upper sash, or to lock the two sashes together, as the case may require, and as the upper sash is provided with a plurality of openings in its longitudinal or vertical rail, the two sashes may be locked together when the upper sash is partly open.

While I have shown and described the preferred embodiment of my invention, it will be understood that minor changes in the details of construction; combination and arrangement of parts may be made without departing from thespirit and scope of the invention as claimed or sacrificing any of the advantages thereof.

What is claimed is a A device of the class described comprising a support including parallel members; a pin loosely mounted in said parallel members, said pin being provided with an elongated longitudinal. slot, a cam member mounted'upon said pinadapted forrotation of the pin to limit longitudinal movement of 5 the latter. y

In testimony whereof I afiix my signature in presence of two witnesses. HARRY W. GOODNOW.
